Paul Alivisatos' team at the University of California, Berkeley, is working to develop a new type of solar cell using nano-sized crystals called quantum dots. Quantum dots are already helping to produce brighter, more vivid color in displays. The ability of solar cells to efficiently process energy in the form of light also makes them an ideal solution to our energy problems.

You may have nanotechnology in your pocket and not even know it. Today's smartphones are much smaller than computers of the past, and yet significantly more powerful, thanks to nanotechnology. Tom Theis with the Semiconductor Research Corporation and IBM, and Ana Claudia Arias at the University of California, Berkeley, explain how nanotechnology has already changed our lives and the exciting possibilities for the future.

How could something only billionths of a meter thick defend against water, dirt, wear, and even bacteria? Working at the nanoscale, scientists and engineers, like Jay Guo of the University of Michigan, are creating protective nanoscale coatings and layers. These surfaces have applications in energy, electronics, medicine, and could even be used to make a plane invisible.

Caltech's Julia Greer is proving that using big and heavy materials is not the only way to build strong, robust structures. Beginning at the nanoscale, her group is constructing materials that are more than 99 percent air yet strong and resilient. These new materials are breaking the rules by behaving in very unexpected ways.
